Two Day Rule

The Rule

One bad day is fine.
Two is a pattern.

You can miss a day. Life happens. But miss two in a row and you lose your streak. And your money. That's the only rule.

How It Works

Set up in under a minute.

01

Pick your step goal

Choose 5K, 7.5K, or 10K daily steps. Or set your own. Steps sync automatically from Apple Health.

02

Put money on it

Commit any amount you choose. Miss two consecutive days and that amount is charged. No subscriptions, no hidden fees.

03

Walk and build your streak

Track your progress in real time. Hit milestones. Find a partner. One day at a time.

Features

Everything you need. Nothing you don't.

Streak tracking

Watch your streak grow day by day. Hit milestones at 7, 14, 30, 60, 100, and 365 days. See your full history on a 30-day heatmap.

Apple Health sync

Steps are pulled straight from Apple Health. No manual logging. Real-time updates every 30 seconds while the app is open.

Works worldwide

Available in 22 countries with 15 local currencies and 4 languages. Commitment amounts adjust to local purchasing power so it feels fair everywhere.

Smart nudges

Send your partner a nudge when they're falling behind. Choose from quick messages or write your own encouragement.

Celebrations

Confetti, haptics, and milestone badges when you hit your goal. The little things that make consistency feel rewarding.

Smart status cards

Context-aware guidance throughout the day. Know exactly how many steps you need and how long it'll take to walk or run them.

Home Screen widgets

Glance at your steps and streak without opening the app. Small and medium widgets keep your progress front and center all day.

Live Activity

Track your walk in real time on your Lock Screen and Dynamic Island. See steps climb, distance covered, and your goal progress without unlocking.

Built Fair

Tough love, not a trap.

We designed Two Day Rule to motivate you, not punish you. Every safeguard is built in from day one.

3 skip days per month

Rest days, sick days, travel. Life happens and the app accounts for it.

Max 2 charges per week

Built-in rate limiting so a rough week doesn't spiral into a rough month.

Data failure protection

If your phone can't track steps, you get the benefit of the doubt. No penalty.

Cancel anytime

No subscriptions. No lock-in. Walk away whenever you want. Though you probably won't.

Start walking.
Stay committed.

Free to download. You only pay when you break the rule.
